4.6.21 for the compound snips, find the dimension b so that a gripping force P wil produce a cutting force of 9P at 1.5 in along the blade from pin A
![Figure P-4-6.19
4-6.19. The frame shown in Fig. P-4-6.19 is supported by smooth
surfaces at A, B, D, and E. The radius of the pulley supporting the load
W is 2 ft. Find the reactions and the total force transmitted by the axle
at C to member BE.
Radius,
= 2.4
Ans.
C= W
4-6.20. Determine the components of the force exerted by the axle
of the pulley in Fig. P-4-6.20 upon the member AC and upon member
CF.
On AC: 0.9W down; on CF: 0.7W down and 0.8W right
Ans.
